WALL-MOUNTED SUBSTATION FOR HEATING AND DOMESTIC HOT-WATER
PRODUCTION (with heat exchangers in parallel configuration)
This type of substation is suitable for small capacity systems, supplied by hot water (or superheated)
for heating (via radiators, fan coils, floor panels, etc.) and production of domestic hot water.
This type of substation is recommended for systems requiring separate and independent
management of the heating and domestic hot water circuits (the system may also be configured
to give precedence to production of hot water over heating).
This type of substation is equipped with the TECHNO SYSTEM TSRE 010 temperature-control system.
With this type of substation, users can:
• directly set the heating set-point and the DHW set-point using easy-access dedicated pushbuttons.
• read the heating delivery, DHW, and recirculation (if applicable) temperatures directly on the
controller display.
• manage heating and DHW production independently, with separate onboard timers and weekly
programs.
• manage heating by external thermostat/timer-thermostat or on the basis of a weekly schedule
programmed in the controller (on/off settings at half-hour intervals.
• set SUMMER or WINTER parameters (DHW only activated in SUMMER mode, DHW and heating
activated in WINTER mode).
• manage heating temperature by the fixed-point or climate-curve method.
• set the set-points for heating, DHW, and recirculation (if applicable) independently.
• with the special Economy function, give precedence to DHW over HEATING.
• lock the heating-side set-point for systems serving floor panels.
• set an ANTI-SCUFF cycle for the HEATING side pump (if installed) when system is in SUMMER mode.
• set an ANTIFREEZE cycle with minimum threshold.
• maintain temperature in the primary circuit via bypass (with ball valve) or managed by the regulator
(with times, intervals, and quantities set via the onboard calendar).
• connect a safety thermostat on the heating side (for floor-panel systems) featuring cut-in signal (by
acoustic alarm and display message).
• connect a safety thermostat on the DHW side (for protection against scalding) featuring cut-in signal
(by acoustic alarm and display message).
• signal sensor malfunction (by acoustic alarm and display message.
• signal excessive pressure in the heating circuit by acoustic alarm and display message and signal
low water level in the heating circuit (and shutdown of the heating side pump, if applicable) by
acoustic alarm and display message).
• reset the values to factory defaults.
• integrate into other systems with accumulators, traditional boilers, and solar panels.
Additionally, this type of substation is prepared for installing devices for:
• managing recirculation via PID with set-point independent of DHW.
• managing an ANTI-LEGIONELLA thermal disinfection cycle via onboard calendar (the system must
comprise recirculation).
• limiting the flow rate on the DHS side.
• limiting the return temperature on the DHS side, with sensor malfunction signal (by acoustic alarm
and display message).
• remote reading of the thermal energy meter.
• remote control.
• managing a GSM or PSTN modem connection, which permits sending SMSs or e-mails for notifying
alarms or malfunctions.
